The flammability of ethyl alcohol is chemical. It's a chemical property because if you change the molecular compound of ethyl, it will have a different flammability.

no
Evaporation is a physical change- it is still alcohol. The change can be undone by colling the air and condensing the ethyl alcohol vapor back to liquid alcohol.
Evaporation of ethyl alcohol is a physical change. This is because evaporation involves only a change in the physical state of the substance from liquid to gas, without altering its chemical composition.
When ethyl alcohol evaporates, it is a physical change because the chemical composition of the alcohol remains the same. Evaporation is a process in which a substance changes from a liquid state to a gaseous state without undergoing a chemical reaction.
No. The chemical structure of ethyl alcohol gas is the same as ethyl alcohol liquid.
Boiling of ethyl alcohol at 79 degrees Celsius is a physical change. It is a reversible process where the alcohol changes from liquid to vapor state without undergoing a chemical reaction.
Evaporation of ethyl alcohol in a watch glass is a physical change, not a chemical change, because it does not alter the chemical composition of the alcohol. The process only involves a change in state from liquid to gas.
Evaporation is a physical change- it is still alcohol. The change can be undone by colling the air and condensing the ethyl alcohol vapor back to liquid alcohol.
The chemical formula for ethyl alcohol is C2H5OH.
It does but it is Not a chemical change its physical change...
Is a physical change as the alcohol is changing states
